The perimeter of a regulation singles tennis court is 210 feet and the length is 30 feet less than four times the width. What are the dimensions of the court? W = L=

L=78 feet W=27 feet

Step-by-step explanation:

lets call the width w and length l.

2 (w+4w-30) = 210 (the bracket is multiplied by 2 because there are 2 lengths and widths)

5w-30=210

divide both sides of the equation by 2 to eliminate the brackets

5w-30=210/2

5w-30=105

add 30 to each side

5w=105+30

5w=135

w = 135/5 = 27

L=27x4-30

L=78
